Ratio is written in x:y. therefore for this case, red:yellow
5 : 7
since the question states that there are 392 yellow poms, the 7 units represents 392 yellow poms. now you have to gind what is one unit and then multiply by 5 to find the number of red poms.
392 represents 7 units
1 unit: 392/7=56
5 units: 5×56=280 red poms
therefore the answer is 280 red poms which is C.
Amy: x skirts
Betty: 2x skirts
Carol: (2x) + 7 skirts
If Amy has 18 less than Carol, than Carol's equation minus 18 equals Amy's equation:
[(2x) + 7] - 18 = x
+18 +18
(2x) + 7 = x + 18
- 7 -7
2x = x + 11
-x -x
x = 11
Input the solution for x into the girls equation to double check.
Amy: 11
Betty: 2(x)
2(11)
=22
Carol: (2x) + 7
22 + 7
=29
Does Amy have 18 less than Carol?
Carol - Amy = 18
29 - 11 = 18
18 = 18
the problem is solved
Answer:
10+5=15
Step-by-step explanation:
Answer:
The given statement is false.
Step-by-step explanation:
We are given the following in the question:
The given statement is
Putting the values on the right side of the given statement
Thus, the given statement is false.
This can be explained with the help of an example:
For x = 3
Translate by vector (4, -2) and reflect over x axis
translate by vector (4, -2) and reflect over x axis
translate by (4, -2) gives (x-4)^2 - 2
reflect over x axis means * -1 = -(x-4)^3 + 2
